Mass Scanning
Can I get banned for mass scanning with https://github.com/robertdavidgraham/masscan or does it slow down any other vms from other persons?

Has anyone ever had their homelab or network hacked? What happened?
Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes.

My home server is frustrating me. Please help me, home server wizards.
Changing the default port does nothing for security. It only prevents some basic brute force or default password scripts. Anyone is able to scan for it in no time anyway (https://github.com/robertdavidgraham/masscan).

Should I be Concerned?
But it should blow away the far-too-common belief that no-one's after you because you're not interesting enough. IPv4 is smaller than we think. It is not difficult to scan the entire ipv4 space in minutes. And every single one of those is going to knock your door on the way past.

Ask HN: Looking for an Old Article
I'm not sure about the article, but the blazingly-fast IP scanner sounds a lot like Masscan. It can scan the entire Internet in 5 minutes and has received a lot of press: https://github.com/robertdavidgraham/masscan . https://rushter.com/blog/how-masscan-works/ is one of many articles about it.

Is my Synology getting port-scanned?
Here's an except from the masscan docs:
- I was hit with ransomware in my Plex server and I'm not sure where it came from. Could a DMZ be the cause?
- PSA: Masscan has changed his IP. Please block the new one on your firewall! Its likely our vps reporting worked.
